Pre-Emergent Grassy Weed Control

Dimension®

DIMENSION (dithiopyr) provides season-long pre-emergence post control of the toughest grasses as well as controlling more small-seeded annual broadleaf weeds than any other herbicide. DIMENSION can be used as a pre-emergent before crabgrass germination, or as a post-emerge application up to 3 leaf tillering. When it comes to weed prevention on golf courses, DIMENSION provides a wide range of application options (spring, summer, and fall) and controls poa annua along with 25 other tough grasses and broadleaf weeds. For best results, apply DIMENSION at the minimum rate of .125-.50 lb. A.I. in northern climates (provides approximately 90-180 day control), and .25-.50-lb. A.I. per acre in southern climates (for 120-180 day control), not to exceed a total of 1.5-lbs. A.I. per acre per year. The components in DIMENSION are not effective unless activated by a minimum .5 inch rainfall or overhead irrigation.

Prodiamine

Prodiamine is a pre-emergent herbicide that is economical, offers a low-dose application rate, and is highly effective against controlling over 30 grassy and broadleaf weeds including crabgrass, goosegrass and poa annua. Prodiamine is non-staining, and offers a wide range of application flexibility. A single application is all that is needed for season-long control, with many turfgrass professionals choosing to apply Prodiamine in the fall after soil temperatures retreat below 50°F. Prodiamine has the lowest water solubility and volatility and stays within the top one half inch of soil. For best results, apply Prodiamine at the minimum rate of .50-lb. A.I. per acre for control up to 12 weeks, 1.00-lb. A.I. per acre for up to 20 week control, and 1.50-lb. A.I. per acre for up to 32 week control. The components of Prodiamine are not effective unless activated by a minimum .5 inch rainfall or overhead irrigation.
